This study was conducted to evaluate the production and reproduction performance of chicken breed under semi-scavenging system of Seka Chekorsa and Omo Nada districts of Jimma Zone. A total of 800 day old chicks were obtained from Debre Zeit Agricultural Research center. 50 day old chicks were distributed with hay box brooder, and the experiment was arranged in a nested design. The result of the current study indicated that male chickens of both breeds in this study reached sexual maturity and slaughter weight within four months in both districts and mature body weights of 1831.25 and 1569.18 g at Seka and 1615.00 and 1586.25g in Omo Nada, respectively for Lohmann dual and Dominant red barred. Although there was no statistically significant difference between the two breeds, Lohmann dual breeds attained age at first egg within 148 days and Dominant red barred (162.25 days) breeds in Seka Chekorsa and 157.50 and 160.25 days, respectively for lohmann and Dominant red barred in Omo Nada district. In general, the current study indicated good performance of Lohmann dual breeds while it needs further study to conclude number of eggs per clutch, number of eggs per hen per year and hatchability for both breeds in both study districts. So this study might be good to consider in the future in other areas.
Key words: Dual purpose breed, on farm evaluation, semi-scavenging, Omo Nada, Seka Chekorsa.
